Instructions for Using Lazy Load Adsense
How to use the lazy load adsense script is very easy, you only need to install one of the lazy load adsense script codes in the head or body of the website, then remove all adsense javascript library tags from the website/blog template.
Change your adsense script :
<script async="async" src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"/>
//or a new version of the javascript library
<script async="async" data-ad-client="ca-pub-1234567890123456" src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"/>
//or updated version
<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-4209467777280582" crossorigin="anonymous"></script>To :
<script type="text/javascript">//<![CDATA[
var lazyloadads=false;window.addEventListener("scroll",function(){(0!=document.documentElement.scrollTop&&false===lazyloadads||0!=document.body.scrollTop&&false===lazyloadads)&&(!function(){var e=document.createElement("script");e.type="text/javascript",e.async=true,e.src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-420946777728xxxx";var a=document.getElementsByTagName("script")[0];a.parentNode.insertBefore(e,a)}(),lazyloadads=true)},true);

How the Lazy Load Adsense Script Works ?
Lazy Load Adsense is completely different from lazy load images because basically lazy load adsense is a scroll event listener, the adsense javascript library in the lazy load adsense script will only be loaded or run when the user scrolls your page.
And that means that adsense ads will only appear when the user scrolls through your blog or website, if there is no page scrolling activity from the user, the ad will also not be loaded (not displayed).
